Question

Quizplus · Accepted Answer

Galactic interactions, especially those involving significant changes in structure and morphology like transforming an elliptical galaxy into a spiral galaxy, typically occur over timescales of several hundred million years. This is due to the vast distances between stars within galaxies and the time it takes for gravitational interactions to significantly alter their orbits and the galaxy's overall structure.
